Bold No.

CMOS technology have one drawback - it is prone to latch up by ionization, because it have The parasitic p-n-p-n thyristor (it is locked in wrong state, to reset must do full power off).

Rad-hardened designs have to deal with this, they used special type of die material and clamping diodes, so their technology essentially different from civilian designs.
